Growing interest in energy efficiency and reduced pollution has increased the demand for green vehicles capable of substantially replacing internal combustion engines. In general, such environmentally friendly vehicles are classified into electric vehicles powered by a fuel cell or electricity, or hybrid vehicles driven by an internal combustion engine and an electric battery.

With respect to the electric vehicle that employs a fuel cell, chemical reaction energy between oxygen and hydrogen is converted into electric energy to thereby generate drive torque. In this process, heat energy is generated by the chemical reaction in the fuel cell, and this heat must be dissipated effectively to ensure the performance of the fuel cell.

Further, even in hybrid vehicles, the driving torque is generated by driving an electric motor using a fuel cell or electricity supplied from an electric battery, together with a torque supplied from the internal combustion engine operated by combustion of fuel. In this regard, the power of the electric motor can only be ensured if the heat generated by the fuel cell, the battery and the engine is effectively dissipated.
